Definitely I was unclear. The (different) mediation by WindowProxy is
good because local global (oxymoronic, ugh -- let's say "this global")
accesses are unmediated and can be super-optimized.
The mediation by trust-label indirection I was referring to above is
for-all-accesses. That is painful.
A compartment per global makes the process of finding the trust-label
(called a "Principal" in Gecko) significantly faster.
